BOYNTON BEACH, Fla. -- A father strangled his two sons in front of their mother and then shot himself so she would live with the pain, according to Boynton Beach Police.

Investigators said Isidro Zavala, 45, walked into his wife's home at 431 S.W. 8th Avenue where he then used a rope to strangle his 11-year-old and 12-year-old sons.

"I don't know why someone would do something like that to the kids. I'm sorry, they didn't deserve it," said Neile Alcin, a neighbor who lives across the street from the home.

Alcin said her children were friends with the Zavala boys and were constantly playing with them in the yard.

"I'm going to miss them because we're not playing with them any more. We're not going to play Playstation no more. We're not going to see each other no more," said Billy Alcin, a friend of the Zavala boys.

Billy Alcin said it was just on Friday where he was flying kites with the two young boys. Billy and his sisters do not understand why the young boys were taken.

"Why? It's like the kids have hearts that are able to love everybody in this world," said Fibie Alcin.

Isidro Zavala's best friend, Mariano Batalla, said he spoke with Zavala on Friday night. Batalla said the two were suppose to go to a party together but then backed out.

"He told me yesterday like at 6:00 p.m. that I got something to do. He said 'have fun,' that's it," said Batalla.

Records show Isidro Zavala and his wife Victoria Zavala had been married since 1993. Document indicate Victoria filed for a divorce in October.

Police said Victoria pleaded with her estranged husband and tried to save the lives of her two sons.

"She said why won't you kill me, why don't you kill me. And he said, no you're going to live with this," said Detective Christopher Crawford of the Boynton Beach Police Department.

Police said according to their records, there is no history of any reports of domestic violence or abuse at the home.

Police also found a note at Isidro Zavala's home to his 19-year-old son, who was not killed. In the note, police said Isidro Zavala told his son how much he meant to him.
